The cardiovascular system plays a very important role in keeping the body alive. It is responsible for transportation of blood around the body. Blood carries many important things such as oxygen and nutrients to various organs allowing them to function properly. Blood also carries waste such as carbon dioxide to the lungs for gas exchange and metabolic waste to the kidneys for filtration and excretion. The cardiovascular system comprises of three different parts these being the heart‚ blood and

Laboratory report investigating the equine respiratory and cardiovascular systems Introduction The respiratory and cardiovascular systems of the horse work together to transport oxygen around the body and play an essential part in providing the horse with its increased need for oxygen during exercise. They allow the musculoskeletal system to use energy to facilitate motion. The cardiovascular system comprises the heart‚ blood vessels and blood. The heart pumps blood around the body

Jogging Activity and Cardiovascular Fitness Today‚ people are becoming more aware of the importance of physical activity. There has been a recent increase in the popularity of fitness activities as hobbies. However‚ despite this increasing popularity in health related activities the large majority of the American population maintains a sedentary‚ unhealthy lifestyle that had led to increased obesity and morbidity rates. According to David Chandler‚ “The largest [obesity] increase has occurred in

The cardiovascular system consists of the heart‚ blood vessels‚ and blood. This system has three main functions: Transport of nutrients‚ oxygen‚ and hormones to cells throughout the body and removal of metabolic wastes (carbon dioxide‚ nitrogenous wastes). Atria: Ventricles: In a four-chambered heart‚ such as that in humans‚ there are two ventricles that operate in a double circulatory system: the right ventricle pumps blood into the pulmonary circulation to the lungs‚ and the left ventricle pumps

through our body. The blood moves through pulmonary circulation and then continues on through systemic circulation. Pulmonary and systemic are the two circuits in the two-circuit system of higher animals with closed circulatory systems. As the heart pumps‚ blood is pushed through our body through the entire circulatory system. Oxygenated blood is pumped away from the heart to the rest of the body‚ while deoxygenated blood is pumped to the lungs where it is re-oxygenated before returning to the heart
Premium Heart Blood Artery
Structure of the heart: The heart is at the centre of the cardiovascular system. It is a hollow muscular pump that drives blood through the arteries‚ which allows it to reach the working muscles and tissues. The heart is split into two halves. The right side of the heart is separated from the left by a solid wall known as the septum. This prevents any blood on the right side coming into contact with the blood on the left side. The right side of the heart sends deoxygenated blood to the lungs in
